26567716-6	2015	Initial ASP(+) uptake was inhibited by a cationic uremic metabolites mixture and by the histamine H2-receptor antagonist, cimetidine.	Aspartic Acid	8-14	histamine receptor H2	Homo sapiens	88-109	
11723228-6	2001	Molecular modeling suggested that the nonconserved Asp-271 in transmembrane domain 7 of gpH2R (Ala-271 in hH2R) confers high potency to guanidines.	Aspartic Acid	51-54	histamine receptor H2	Homo sapiens	106-110	
11723228-7	2001	This hypothesis was confirmed by Ala-271-->Asp-271 mutation in hH2R-GsalphaS.	Aspartic Acid	46-49	histamine receptor H2	Homo sapiens	66-70
